Beit known thatCHARLES W. CLEWLEY, late of Cranston, in the county of Providence, and State of Rhode Island, and now deceased, did, while in full life, invent certain'new and useful Improvementsin Machines for Making Eyelets; and I, GEORGE P. TEW, of Cranston, in said county and State, administrator upon the estate of saidClIARLE-S W. CDEWLEY, dollereby declare that the following specification, taken in connection with the drawings making a part of the same, is a full, clear, and exact description thereof.

Figure 1 is a side elevation. l

Figure 2 is a plan.

Figure 3 is a'section on the line :lf-2 in' lig-2.

On the sixth day of September, A. D. 1859, there were granted by the United States, to the said CHARLES W. CLEWLEY, certain'Lettcrs Patent of that date, and numbered 25,318, for an improvement in machines for making watch-rims, 3ro., whereby there was secured to the said CLEWLEY the combination, substantially as described in the' schedule accompanying the same, of the male and female plungers for thepurposes therein set forth.

`Andai'tcrwards, on tho nineteenth day of June, A. D. 1860, there were also granted by the United States, to the said CHARLES W. CLEWLEY, certain other Letters Patent of that date, and numbered 28,737, for an improvement in the devices for making the rims of watch and locket-cases, whereby there was secured to the said CLEWLEY the combination of a diecutter and a plunger, substantially as described in the schedule :accompanying the same, for the purposes therein set forth. l v

And the said CLEWLEY being so possessed of said Letters Patent forl said inventions and improvements, conceived the idea that the two subjects'ofinvention could themselves be combined together and incorporated into a machine for making eyelets, and with that view he produced the machine hereinafter desoribed,rwhich Vpllbodies the inventions above named, andcertain improvements and additions hereinafter particularly mentioned, to enable the two classes of instruments used in making locket-rims to Work together iu'combination, to effect( thcmaking of an eyelet.

In the accompanying drawings, A is the rectangular bed or frame'upon which the parts of the machine are mounted.- 4

A reciprocating motion is given to the compound instrument, B, presently to be described, in any convenient way, and in this instance by means of a'link, C, connecting the same with a crank upon the main shaft D.

The compound'instrumentfreferred to consists of a die, a, and female cutter, b, substantially the same as" that described in the above-mentioned patent, granted to the said CLEWLEY, June 19, A. D. 1860, and numbered 28,737; but in addition, the outside of the 'die constitutes a lmale cutter or plunger, c, to act in combination with the stationary cutter, d, toA cut out from a stripzthe planchots or circular disks of metal from which'the eye-v lets are to be formed. I

E is a block of steel, formed with a circular opening, d', vvhich has a cutting-edge. The opening corre-V sponde in diameter with the diameter of ther'nale cutter 1:,.1vhich is to enter therein. In the centre of this opening stands a fixed stud or punch of steel; e, madesuiciently tapering to correspond with the die a, and to give the interior form to the cyelet. It has also a tip, [hat the extreme end, which is cylindrical, and whose olc'e is to act in combination with thc'female cutter b, to .punch o ut the bottom of the eyelet, and is: the equiv alen-t ofthe plunger described in said patent, numbered 28,737, with the dii'erence that in this case the punch is stationary. l Y

The rear portion of the block E is cut away as shown in fig. 3, to'give4 room for the collarf which surrounds the stud e for a portion of its length, and the office of which is to turn theiianch of the eyelet, and at the proper time to strip it olf the stud. This collar, inV combination `with the stud e, is substantially the malel and female plunger described in the said CLEWLEYS patent above mentioned, dated September 16, 1859, and numbered 25,318.

AWe will now suppose the strip of metal stock to be presented by meansof the feeding-rollers F F', which are geared together andoperated by aratchet-motion, G,`eonneeted with the main sl1aft, and arranged in a wayfamiliar to all machinists, so as to cover the circular opening in the block E.

The compound instrumentB, consisting, as already s tated, of a male cutter, c, 'a die, a, and a female cutter, b, comes forward, andthe' malo cutter c, in combination with the female cutter d, in the stationary block E, cuts out aplanchet. l

This vplanchet, by the continued onward movement of B,Ais'shapedb'y the tapering'portion of the stud e, in

combination with the die a, into a bell-shaped cup. The cylindrical tip h acting as a male cutter, in combination with the female cutter b, at the same time punches out the bottom. The rim of the planchct is also at the same time turned so as'to form a ianch bythe aidjof the face of the collarf. l

The eyelet is now formed, but remains upon the tip h ofthe stud e until the collarf strips it-oil'. The collar Vis made -to do 4this oiiico as B retreats, by meansof the rod O, connected at oneend with the reciprocatingcrosshead G', andat the other end -with the collar.

Inasmuch as the small'circular-disk which is cut from the bottom ofy the eyeletremains at the bottom of thedie,'it is necessary to expel the samebefore fthe next eyelet is formed. This is eil'ected by the piston-rod Hrwhich is fitted to slide easily in the axis of the compound instrument' B, and is capable of moving forward Whenl suitably impelled into the die a. from the rear. As the cross-head Gr is retreating, a projecting block, I, pivted to its under slide, strikes against a flat spring, J, and bends it backward until the line in which the f' block travels becomes atangent to the arc described by the end of the spring, when the. latter is released and strikes the' bent shank ,7c of the. piston a blow, whichcause's it to dart forward and drive out the disk from the die. v A

As thecross-head moves forward again, the block. I, which has its opposite face rounded, and ha's also 'a slight rocking motion on its pivot' 7c, is enabled to override the and of the spring, and be in position to repeat vits function upon the next return of the cross-head. I

What is claimed as the inventionof thesaid CHARLES W. CLEWLEY, and is sought to be secured by Letters Patent, is y d 1. The compound instrument B, composedoi:` amale cutter, c, a die, a, and a female cutter, b, in lcombina-- tion,`constituting 'the moving instruments in the formation of an eyelet, substantially as described.

2. The combination of the above-described compound -'nstrurnent B with the stationary female cutter d,

, former e, male cutter It, and collar f, substantially as described.

3. The piston H, in combination with the die a, arranged and operated substantially as described, for th'e 'purposes specified.
